Primary study area is outlined by bos. Hypothetical blind thrusts are schematically indicated by dashed thrust fault symbols - are purely schematic at present. Mt. Tamalpais and Bolinas Ridge are identified

Earthquakes are not unusual in the San Francisco Bay Area, but a team of Penn State geoscientists believes that the hazard may be greater than previously thought because of a hidden fault under Marin County.
"We think we have evidence that there is an additional earthquake hazard in the San Francisco area due to a blind thrust fault," says Dr. Kevin P. Furlong, professor of geosciences. "Blind thrust faults are notorious because they are hard to find until an earthquake occurs on them. A blind thrust fault caused the 1994 Northridge earthquake."
The San Francisco Bay Area has a variety of known faults running through it. The San Andreas fault runs on the west, while the Hayward fault is on the east and shifts into the Rodgers Creek fault northeast of the city. The San Gregorio fault, west of the San Andreas, meets that fault near the Golden Gate Bridge.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
